  • Conflicts between CSS Menu and Image as Links

    - by user354051
    There is logo on the top (image as link) and other images as links. These links are not working in FF and safari. The problem is with css/ul/li based navigation menu. If I remove the menu html code, images as links are working fine. The css based navigation menu is based on this code: /* Navigation Menu */ #nav a, #nav a:hover, #nav a:focus {...} #nav {...} #nav ul {...} #nav .menu .level1-li {...} #nav .menu a {...} #nav .menu a.level1-a {...} #nav .menu .sub {...} #nav .menu .sub a {...} #nav .menu a:hover {...} I am not much familiar with CSS and this is the example I have downloaded from the web. It seems "a" is doing something wrong here. Prashant

  • Drupal - editing tab options for a content type not showing up

    - by easement
    I'm working on a D5 site and a lot of the content types have the menus at the top of the edit page. Examples: Overview | Grants | Dev load | Dev render | Edit | Revisions | Track | Workflow Overview | Dev load | Dev render | Edit | Revisions | Track | Workflow | Node queue | RelatedContent I'm not sure where these tabs come from, but I need to enable the menu for a content type that doesn't have them visible. I checked the workflow setting and the content type in question was specified to use workflow. So there should be at least another tab in addition to edit. The end goal is to have revisions show up in the menu, but I need to get the menu showing first. Any ideas where to start looking?

  • Load Balancing and Failover for Read-Only PostgreSQL Database

    - by Eric J.
    Scenario Multiple application servers host web services written in Java, running in SpringSource dm Server. To implement a new requirement, they will need to query a read-only PostgreSQL database. Issue To support redundancy, at least two PostgreSQL instances will be running. Access to PostgreSQL must be load balanced and must auto-fail over to currently running instances if an instance should go down. Auto-discovery of newly running instances is desirable but not required. Research I have reviewed the official PostgreSQL documentation on this issue. However, that focuses on the more general case of read/write access to the database. Top google results tend to lead to older newsgroup messages or dead projects such as Sequoia or DB Balancer, as well as one active project PG Pool II Question What are your real-world experiences with PG Pool II? What other simple and reliable alternatives are available?

  • Path element of Siverlight issue

    - by George2
    Hello everyone, Suppose I have the following XAML code, my confusions are, (1) I do not know the exact meaning of Data attribute, especially items starts with letter M/C, (2) there is no special configuration for TransformGroup (all using default settings), why put the TransformGroup here? <Path Height="2.75" Width="2.75" Data="M2.75,1.375 C2.75,2.1343915 2.1343915,2.75 1.375,2.75 C0.61560845,2.75 0,2.1343915 0,1.375 C0,0.61560845 0.61560845,0 1.375,0 C2.1343915,0 2.75,0.61560845 2.75,1.375 z" Fill="#FF9F9B9B" Stretch="Fill" Stroke="#FF000000" StrokeThickness="0" Canvas.Top="7" x:Name="p3"> <Path.RenderTransform> <TransformGroup> <ScaleTransform/> <SkewTransform/> <RotateTransform/> <TranslateTransform/> </TransformGroup> </Path.RenderTransform> </Path> thanks in advance, George

  • How to determine position (x,y) relative to the page of every character inside spans through javascript?

    - by Fernando
    This is as simple as I can get. I will have several spans randomly positioned on the screen through something like: $(".hidden:first").css('-webkit-transform','rotate('+((0.5-Math.random())*40)+'deg)'); $(".hidden:first").animate({ left: '+=' + (((screen.width-800-224)/2) + Math.random()*800), top: '+=' + (50+Math.random()*600) } [...] and later on I would like to iterate through every char of every of those elements (that are randomly position and have random rotation), and I would need to discover the (x,y) position of every character on the screen so I can colorize it, forming certain draws according to certain functions. Is this easily achievable? I am really inexperienced at javascript. Thanks. Fernando.

  • How can one make a web-site accessible only when someone has a dongle?

    - by Brian M. Hunt
    Suppose you want to add an extra layer of credentials on top of a SSL-encrypted login/password, but you don't want to increase complexity to the user. Is there a way to add the requirement of the possession of a dongle to web-server authentication schemes with existing cross-platform browser capabilities? In other words, to get access to the web-site, you would need a username, password, and a USB dongle that has been plugged into the client computer. The dongle would presumably do some sort of challenge/response. It'd be ideal if this dongle solution worked with Firefox automatically or with the simple addition of a plugin. Thoughts and suggestions are appreciated.

  • Canvas element covering the entire screen?

    - by Stefan Kendall
    I'm trying to use <canvas> in iPhone Safari, and if I place the element in the body, there are unused pixels to the left and top of the element. I tried specifying margin:0;padding:0 with CSS to no avail. What's going on here? <html> <head> $(document).ready(function() { $('#screen').attr("height", $(window).height() ); $('#screen').attr("width", $(window).width() ); //prevent scrolling $(document).bind('touchstart touchmove', function(e) { e.preventDefault(); }); }); </script> </head> <body> <canvas id = "screen"> </canvas> </body> </html>

  • How to sort a Ruby Hash by number value?

    - by dustmoo
    Hi everyone, I have a counter hash that I am trying to sort by count. The problem I am running into is that the default Hash.sort function sorts numbers like strings rather than by number size. i.e. Given Hash: metrics = {"sitea.com" => 745, "siteb.com" => 9, "sitec.com" => 10 } Running this code: metrics.sort {|a1,a2| a2[1]<=>a1[1]} will return a sorted array: [ 'siteb.com', 9, 'sitea.com', 745, 'sitec.com', 10] Even though 745 is a larger number than 9, 9 will appear first in the list. When trying to show who has the top count, this is making my life difficult. :) Any ideas on how to sort a hash (or an array even) by number value size? I appreciate any help.

  • IE Cannot open the internet site (no JS on the page)

    - by Nic Hubbard
    I know that there are many posts about this on Stackoverflow, but this one is different. All of the other fixes to this have to do with javascript, but I don't even have javascript on my page. None. And I am still getting this error. Was there any other reasons why this error was being caused? Also, it only happens when I visit my top navigation links, rather than the page directly from the url. Take a look at: http://www.mayandivers.com/see EDIT: This is happening in IE6/7.

  • Adding custom columns to Propel model?

    - by Hard-Boiled Wonderland
    At the moment I am using the below query: $claims = ClaimQuery::create('c') ->leftJoinUser() ->withColumn('CONCAT(User.Firstname, " ", User.Lastname)', 'name') ->withColumn('User.Email', 'email') ->filterByArray($conditions) ->paginate($page = $page, $maxPerPage = $top); However I then want to add columns manually, so I thought this would simply work: foreach($claims as &$claim){ $claim->actions = array('edit' => array( 'url' => $this->get('router')->generate('hera_claims_edit'), 'text' => 'Edit' ) ); } return array('claims' => $claims, 'count' => count($claims)); However when the data is returned Propel or Symfony2 seems to be stripping the custom data when it gets converted to JSON along with all of the superflous model data. What is the correct way of manually adding data this way?

  • What exactly is a Monad?

    - by WeNeedAnswers
    Can someone please explain to me what a Monad is. I think I grasp Monoids and I grasp that they basically control the input of state into a system. I just look at the text in Haskell and glaze over. A simple example in python would be great. My current understanding is that a Monoid is a procedural piece of code that needs to be read from top to bottom in sequence with the output being the input for the function. I think that I may even got that wrong, but hey I am here to learn.

  • How to obtain Bing maps like InfoWindow in Google Maps?

    - by BillB
    I'm using Google Maps v3. I really like the InfoWindows found in Bing, as opposed to Google. Screenshots & functionality found here comparing the two: http://www.axismaps.com/blog/2009/07/data-probing-and-info-window-design-on-web-based-maps/ Question: How can I replicate Bing like InfoWindows while using Google Maps v3? UPDATE: To be more specific, what I like about Bing's InfoWindows include: - The pointer dynamically changes sides from left/right/bottom/top, as opposed to Google limited to only have the InfoWindow pointer on the bottom - Bing's InfoWindows use less space - You can configure Bing's InfoWindows to pop up outside of the map bounders so that you don't have to autopan the map to display the marker's InfoWindow

  • Pylons and Facebook

    - by Nayan Jain
    The following is my oauth template top.location.href='https://graph.facebook.com/oauth/authorize?client_id=${config['facebook.appid']}&redirect_uri=${config['facebook.callbackurl']}&display=page&scope=publish_stream'; Click here to authorize this application When I hit the page I am prompted to login (desired), upon login I am redirected in a loop between a permissions page and an app page. My controller looks like: class RootController(BaseController): def __before__(self): tmpl_context.user = None if request.params.has_key('session'): access_token = simplejson.loads(request.params['session'])['access_token'] graph = facebook.GraphAPI(access_token) tmpl_context.user = graph.get_object("me") def index(self): if not tmpl_context.user: return render('/oauth_redirect.mako') return render('/index.mako') I'm guessing my settings are off somewhere, probably with the callback. Not to sure if it is an issue with my code or the python sdk for facebook.

  • measuring performance - using real clicks vs "ab" command

    - by shanyu
    I have a web site in closed beta, developed in Django, runs with Mysql on Debian. In the last few days, the main page has been showing a slowdown. For every ten clicks, one or two receives extremely slow response (10 secs or more), others are as fast as they used to be. When I was searching for the problem, I ran into this issue that I couldn't grasp: top command shows that when I request the main page, mysql shoots up to 90% - 100% cpu usage. I get the page just as the cpu use gets back to normal. So, I thought, it is db. Then I called ab with parameters -n 1000 -c 5, I got decent performance, about 100 pages per second, just as it was before the slowdown. I would imagine a worse performance as 10-20% of requests take 10 secs to load. Is this conflict between ab and "real" clicks normal, or am I using ab in a wrong configuration?

  • iPhone CoreData: How can I track/observe all changes within a subgraph?

    - by D Carney
    I have a NSManagedObjectContext in which I have a number of subclasses of NSManagedObjects such that some are containers for others. What I'd like to do is watch a top-level object to be notified of any changes to any of its properties, associations, or the properties/associations of any of the objects it contains. Using the context's 'hasChanges' doesn't give me enough granularity. The objects 'isUpdated' method only applies to the given object (and not anything in its associations). Is there a convenient (perhaps, KVO-based) was I can observe changes in a context that are limited to a subgraph?

  • UISearchDisplayController's full-screen background intercepts touch events in iOS 7

    - by tba
    I have a UITableview that doesn't take up the whole screen (screenshot). Everything worked fine in iOS 6. But in iOS 7, when the user searches, the search result table takes up the whole view (screenshot). To fix this, I tried setting the frame manually as described in this answer. The appearance is now correct (screenshot), but now the "<" button in the top left doesn't receive tap events when the search results table is displayed. It seems the searchResultsTableView is adding a full-screen background view that is intercepting touch events. To prove this, I added this code to didShowSearchResultsTableView: controller.searchResultsTableView.superview.backgroundColor = [UIColor blueColor];` This screenshot confirms my hypothesis. How can I fix this to allow the "<" button to receive tap events? I want to avoid modifying controller.searchResultsTableView.superview so that my change doesn't break in future versions of iOS. And what change in iOS 7 caused this behavior to start happening?

  • Silverlight 4 NewBie Question

    - by codemnky
    I am watching a video from Silverlight.net website about DataForm. There is no source code download, so I am typing in the code as I watch the video. Unfortunately I can't replicate what is shown in the video. there are several issues. I am going to list out only the first 2 1) The presenter shows a simple class inside DataForm that has a icon at the very top of the data form that upon clicking it makes the DataForm editable and a save button appears at the bottom. I did'nt get the same thing when I ran my code against Silverlight 4 or Silverlight 3 2) Than he goes on to show that if you mark your class [Bindable(false)] you shouldn't see anything in your page. I did that but my form still shows all the properties I stopped after these 2 issues. If the features being talked about in this video were deprecated in the final release than this video should have been taken off the site. can anyone help me with this??

  • What are the lesser known but cool data structures ?

    - by f3lix
    There a some data structures around that are really cool but are unknown to most programmers. Which are they? Everybody knows linked lists, binary trees, and hashes, but what about Skip lists, Bloom filters for example. I would like to know more data structures that are not so common, but are worth knowing because they rely on great ideas and enrich a programmer's tool box. PS: I am also interested on techniques like Dancing links which make interesting use of the properties of a common data structure. EDIT: Please try to include links to pages describing the data structures in more detail. Also, try to add a couple of words on why a data structures is cool (as Jonas Kölker already pointed out). Also, try to provide one data-structure per answer. This will allow the better data structures to float to the top based on their votes alone.

  • Is there an easy way of obtaining the total page response time in ASP.Net?

    - by Earlz
    Hello, commonly on say PHP or other web frameworks getting the total response time is easy, just start the timer at the top of the file and stop it at the end. In ASP.Net there is the whole Page Lifecycle bit though so I'm not sure how to do this. I would like for this response time recording to take place in a master page and the response time show up in the footer of pages. What would be the best way of doing this? Is there something built in to ASP.Net for it? Is it even possible to include the OnRender time?
